Title: Caloric Content of Food
Purpose: To determine the caloric in food, and compare that to the label on the package.
Procedures: I used beaker of water and thermometer, and a burning food source with a scale.
Data Tables:
Food Item Description Nut: Cashew Marshmallow: Jumbo Other Sampler: Cracker
Mass of food, cup, and clamp - initial 29.7 4228 30.9
Mass of food, cup, and clamp - final 29.3 38.0 29.4
Mass of burned food 0.9 9.6 0.9
Observation of flame 2:38.57 Steady not intense 1:48.57 rapid burn but not hot 1:48.87 steady, hot, very intense
Water temp - initial 23 C 37 C 54 C
Water temp - final 38 C 54 C 78 C
Change in temp 15 C 17 C 24 C
Q - Energy released (kcal/g) 10.4 .85 3.65
Energy est. on package (kcal/g) 9.9 3.3 4.9
Percent Difference 2 80 15
Determination of cal. according to Atwater Factor (kcal/g) .05 .01 .02

Questions:
A. Same – water, thermometer, heat application
Different – turbine, not flame
B. Heat escaping and math being off
Having a better way to trap heat.
C. The cracker burned the best and hottest.
More carbs and fats
Body uses carbs and fat as fuel.
D. Protein is not broken down into energy.
E. Marshmallow has no fat.
F. No, weight used, they round up or down in their math.
Conclusion: In this experiment I learned that the amount of energy released by food is needed to fuel the body. I also learned that what the package shows in not always the truth and that you could be taking in more or less than what you
